(3) Petitions must be based on the discovery of new evidence or on a showing that the Board's findings are erroneous. (i) Petitions based on the discovery of new matter shall: Identify the new matter; contain affidavits of prospective witnesses, authenticated documents, or both, or an explanation of why such substantiation is unavailable; and state why the new matter was not available prior to Board's adoption of its findings.

(ii) Petitions based on a claim of erroneous findings shall set forth in detail the grounds upon which the claim is based.
